A typical prior art fire simulating device comprises a water tank and an ultrasonic transducer arranged to transmit ultrasound through the water in the water tank and hereby provide mist (clouds of water vapour). A fan is typically arranged to create pressure gradient that draws the mist upwards through an outlet structure, through which the mist leaves the fire simulating device. The mist is intended to simulate smoke. By illuminating the mist from below by a light source, it is possible to simulate flames. By varying the intensity of the light one can simulate the glowing nature of a fireplace.

Accordingly, the control unit receives the data collected by the temperature sensor.
The fire simulating device 2 comprises a water level sensor 18 arranged and configured to detect the water level of the mist chamber 28. The measurements made by the water level sensor 18 are used to keep the water level constant or at least within predefined range. In one embodiment, the water level is kept at a predefined level at approximately 15 mm. In one embodiment, the water level is kept at a predefined level at approximately 20 mm. In one embodiment, the water level is kept at a predefined level at approximately 10-35 mm. In one embodiment, the water level is kept at a predefined level at approximately 15-30 mm. In one embodiment, the water level is kept at a predefined level at approximately 20-25 mm. In one embodiment, the water level is kept at a predefined level at approximately 22 mm. In one embodiment, the switch 18 may be a float switch. By keeping the water level at a predefined level or within a predefined range, it is possible to control the mist generation rate. If the water level, however, is not kept at predefined level or within a predefined range, the mist generation rate cannot be controlled because the mist generation rate depends heavily on the water level.
If the water level in the mist chamber 28 decreases to a level below the predefined level or range, the valve 22 will open so that water will flow from the tank 20 via the inlet 24 into the mist chamber 28. In the mist chamber 28 mist will be generated by means of the atomizer 56. The atomizer 56 comprises an ultrasonic transducer arranged to transmit ultrasound through the water in the mist chamber 28 and hereby generate mist.
DK 181285 B1 17
The fire simulating device 2 comprises a blower (see Fig. 7A and 7B) arranged and configured to blow air into the mist chamber 28. Hereby, the pressure inside the mist chamber can be controlled by regulating the activity of the blower. In a preferred embodiment, the control unit is connected to the blower, the valve 22 and to the water level sensor 18, wherein the control unit is configured to control the activity of the blower.
The size of the flames can be controlled by regulating the activity of the atomizer and the flow of air generated by the blower.
In one embodiment, a pressure senor is arranged and configured to detect the pressure inside the mist chamber 28. In one embodiment, the control unit is communicatively connected to the pressure sensor.
Hereby, the control unit can regulate the activity of the blower in dependency of the pressure inside the mist chamber 28.
A divider structure 14 is arranged in the mist chamber 28. The divider structure 14 comprises an inclined plate that extends basically from the lower left corner to the upper right corner of the mist chamber 28. One or more openings are provided in the inclined plate (this can be seen in
Fig. 11). The one or more openings allow the mist to be guided along the divider structure 14 in a manner, in which the mist can be mixed with air blown into the mist chamber 28 and be distributed homogenously along the length of the opening of the outlet portion 12.
Accordingly, by means of the divider structure, the mist will be guided upwardly in the mist chamber 28 in such a manner that the mist will be evenly distributed along the length of the opening in the outlet portion 12. The mist will be heated by the heating element 10 when the mist passes the heating element 10.
In one embodiment, the heating element 10 extend along the entire
DK 181285 B1 18 length of the distal opening in the outlet portion 12. Hereby, the mist along the entire length of the distal opening in the outlet portion 12 will be heated.
The heating element 10 may, however, extend along less than the entire length of the distal opening in the outlet portion 12.
An air chamber 16 is provided in the mist chamber 28. The air chamber 16 receives air from the blower (not shown). The air chamber 16 is in fluid communication with that part of the mist chamber 28, in which the mist is generated. Accordingly, when mist leaves this part of the mist chamber 28, the air blown into the air chamber 16 will balance the pressure inside the mist chamber 28.
When the light emitted by the light sources 8, 8’ illuminates the mist, the mist will resemble fire. Mist that is not illuminated by light will, however, resemble smoke.

The diameter d: of the heating element 10 is only slightly smaller than the inner width d, of the distal portion of the outlet portion 12. Accordingly, the mist 32 is located close to the heating element 10 when passing the heating element 10. Accordingly, at efficient heating of the mist can be achieved. The heating element 10 has a circular cross section. However, the heating element 10 may have a rectangular cross section or another cross section.
In one embodiment, the diameter D; of the heating element 10 is larger than the diameter of the temperature sensor 30. In one embodiment, the inner diameter or width D, of the distal portion of the outlet portion 12 is less than twice as large as the diameter D; of the heating element 10.
